The Green Bank fast pulsar survey (gb4) published its results in 1996 and 1997 with a total of 5 new pulsars discovered. It detected a grand total of 78 pulsars. The fastest pulsar discovered was J1518+4904 with a period of 40.93499 milliseconds and the slowest pulsar was J2302+6028 with a period of 1.2064 seconds.
The smallest pulsar dispersion measure was J1518+4904 with a DM of 11.61139 pc/cc and the largest pulsar dispersion measure was J2302+6028 with a DM of 156.7 pc/cc. There were a total of 594 pulsars known before the first discovery was published. This survey increased the total amount of known pulsars by 1.0%.
There were 2 papers written about the discoveries of this survey: PSR J1518+4904: A Mildly Relativistic Binary Pulsar System, The Green Bank Northern Sky Survey for Fast Pulsars.
